When ordering B grade tiles, please plan for 15-20% to be lost due to color variation, bowing, chipping and breakage. Our heavily discounted prices take this into consideration so you can purchase more tiles and still be well under competitorsí price. Please note, your contractor must be informed that this tile is B grade/second choice, and it will require them to be conscious of that when laying the tile (variations in color, chips, bowing, height, etc.). Most partially broken or bowed tiles can be cut to be used under counter edge, in closets, etc. Please purchase 15-20% more than your necessary square footage to make up for the total loss of any tiles.
